A method for controlling a cooling device within a projecting system is provided. The cooling device cools the projecting system with a predetermined period after the illumination device of the projecting system is turned off. Then, after the projecting system is restarted, it is detected that whether the illumination device is lighted or not. As the illuminating device is not lighted, the predetermined period is extended.

A method for determining whether to activate an illumination source includes directing an air current across at least a portion of the illumination source and across at least a portion of a temperature sensor. The method also includes sensing the temperature of the air current with the temperature sensor and determining whether to activate the illumination source based on the temperature of the air current.
摘要:
A barrier discharge lamp wherein an ultraviolet radiation flux is emitted by a working gas confined between two coaxial silica tubes connected at both ends. The gas is subjected to electrical pulses supplied by a generator and applied between an inner and an outer electrode including a conductive window. The cooling is provided by a driven air flow, in particular in the tube, by a fan. Its efficacy is enhanced by a radiator associated with the inner electrode, and by a convective working gas flow. The flow is provided not only around the tube in the vicinity of the electrodes, but in an axial plane with channels on either side of the tube at both ends thereof spaced apart from at least one of the electrodes. The invention is applicable to industrial processes and medical treatments using ultraviolet radiation with very small spectral width, and for treating psoriasis and vitiligo.
